With heavier halides, the coordination quantities are reduced. The other trihalides are dimeric or polymeric with tetrahedral 4-coordinate aluminium facilities.[g] Aluminium trichloride (AlCl3) provides a layered polymeric framework under its melting position of 192.4 °C (378 °F) but transforms on melting to Al2Cl6 dimers. At better temperatures All those more and more https://aluminiumgreenhouse90011.ampedpages.com/a-secret-weapon-for-aluminium-greenhouse-64419978
